y/n Stark(Eva stark) and Sarah Rogers are the kids of Iron Man and Captain America. They are best friends. They were kidnapped by hydra when they were 14 and were experimented on and tortured for almost two years, yn got it a lot worse and ended up earning a very dangerous power that she learned to control and I prosthetic arm like Bucky’s as they tried to make me a weapon like him and have dangerous reactive powers, Sarah got it more simple, and they had been put in different rooms, right next to eachother so they could stick together - until the Avengers found and rescued them and it has been one year since they were rescued and are doing better than ever
